Memory Settings for CJ-series Units

These settings are provided to specify the area type and size of the memory used for CJ-series Units when the Serial communications mode is set to Host Link (FINS).

The host link (FINS) protocol accesses only the memory used for CJ-series Units out of the entire memory available in the CPU unit.

Nevertheless, the NX1P2 CPU Unit does not have memory used for CJ-series Units in the default setting. Therefore, in order to use the host link (FINS) protocol, you need to generate memory used for CJ-series Units in the NX1P2 CPU Unit. The memory settings for CJ-series Units are used for this purpose.

4-2-4 Programming

Assign the user-defined variables that are used in the user program on the CPU Unit to the memory used for CJ-series Units that will be accessed by the NB-series Unit by using AT specification.

Then, create the user program for communicating with the NB-series Unit.

Refer to the NJ/NX-series CPU Unit Software User’s Manual (Cat. No. W501) for memory used for CJ-series Units and AT specification.

The NX1P2 CPU Unit performs programless communications with NB-series Units using the host link (FINS) protocol.

The host link (FINS) protocol accesses only the memory used for CJ-series Units out of the entire memory available in the CPU unit based on address specification.

In other words, the CPU Unit uses the memory used for CJ-series Units to communicate data with NB-series Units.

On the other hand, the NX1P2 CPU Unit uses variables for all processing tasks, for example, to exchange I/O information with external devices, perform data calculations, and so on.

Therefore, to access memory used for CJ-series Units from the user program on the CPU Unit, you need to assign user-defined variables to it. This assignment of user-defined variables to memory used for CJ-series Units is called AT specification.

The following describes programless communications with E5C Digital Temperature Controllers.

4-3-1 Overview

The NX1P2 CPU Unit supports programless communications with E5C-series Digital Temperature Controllers (hereafter E5C Controllers) using the host link protocol.

In programless communications with E5C Controllers, you can read and write E5C parameters and run/stop the Controller via the memory of a Programmable Controller (hereafter PLC). Because E5C Controllers communicate with a PLC automatically, there is no need to create a communications program.

4-4 Connection with Modbus-RTU Slaves

The following describes data exchange between the CPU Unit and Modbus-RTU slaves.

4-4-1 Overview

The NX1P2 CPU Unit can exchange data with Modbus-RTU slaves by using instructions to send a Modbus-RTU command and receive a response.

To use this function, you mount a Serial Communications Option Board on the NX1P2 CPU Unit, set its Serial communications mode to Modbus-RTU Master, and connect their serial ports together.

The processing of the Modbus-RTU protocol and message frame format is handled by the instructions to send a Modbus-RTU command and receive a response.

Therefore, you can easily create a program to exchange data with Modbus-RTU slaves.

Refer to the NJ/NX-series Instructions Reference Manual (Cat. No. W502-E1-17 or later) for the specification of instructions.

The frame format of Modbus-RTU commands is as follows.

Slaves

Address

1 byte 1 byte 0 to 252 bytes 2 bytes*

* The byte order of the CRC code is lower byte, then higher byte.

Refer to MODBUS Application Protocol Specification for the specifications of the MODBUS communications protocol. You can obtain MODBUS Application Protocol Specification from MODBUS Organization, Inc.

Manuals and technical materials for Modbus-RTU slaves

When you use a two-wire type of RS-485, be careful as follows:

The CPU Unit fails to receive the response frame if a response frame from the Modbus-RTU slave is sent too soon for the Modbus-RTU command frame.

When a receiving of the response frame failed, the following adjustments are needed.

• Adjustment on the CPU Unit side

Increase the number of retries of serial communications instructions for the Modbus-RTU master in the user program.

The number of retries is set by an Option.Retry (Retry count) input variable of the Modbus-RTU master instructions.

• Adjustment on the Modbus-RTU Slave side

Increase the wait time from when the Modbus-RTU slave receives a command until it sends a response.

Serial Communications Devices

The following describes data exchange between the CPU Unit and general-purpose serial communications devices.

4-5-1 Overview

The NX1P2 CPU Unit can exchange data with general-purpose serial communications devices by using the instructions to send and receive data in No-Protocol mode.

To use this function, you mount a Serial Communications Option Board on the NX1P2 CPU Unit, set its

Serial communications mode to No-Protocol, and connect their serial ports together.

4-5 Connection with General-purpose Serial Communications

Devices

The instruction to send data in No-Protocol mode refers to an instruction to output the specified data from the specified serial port without converting it.

The instruction to receive data in No-Protocol mode refers to an instruction that reads data received at the specified port into the specified variable without converting it.

Refer to the NJ/NX-series Instructions Reference Manual (Cat. No. W502-E1-17 or later) for the specification of instructions.

4-5-1 Overview

NX-series NX1P2 CPU Unit Built-in I/O and Option Board User’s Manual (W579)

To enable the CPU Unit to exchange data with general-purpose serial communications devices by using the instructions to send and receive data in No-Protocol mode, you must program the communications procedure (protocol) for the remote device.

For example, program the sequence processing and retry processing between the command and the response, data type conversion processing, branching processing, and other processing steps to be performed based on the communications protocol of the remote device.
